Ivy has a good idea, and sparks one here as well. How about
"zig-zag"ing the dipole in a 'schematic resister object' manner ?

This would seem to me that it would allow you to fit the 105' length
into an 80' space, but since RF likes to travel in set 'distances' at
the various freqs, and the 'zero crossing points' would be greatly
changed (physically) with this array, I'm not sure WHAT it would
do to your SWR. Maybe an Elmer on the echo can answer that one.
It might be SO severe that the array would be unusable at ANY freq,
and could quite POSSIBLY create some dangerous potentials.
Have you checked out the other types of 'longwire' arrays like;
the Sterba Curtain, Bruce Array, Windom, etc ? Just to name a
few that I remember seeing in the handbook from years ago.
